exported retargeted animation is only 24 keyframes long (scene is set to 34 keyframes and animation is 34 keyframes long)
I'm not sure exactly what's causing this to work, but if i bake a new animation with the skeleton (output properties and such set to desired frame length, it will create a new animation. If i go into the NLA editor, push down the action as an NLA strip,

then head over to the action clip section in the N menu, select my newly baked clip,

go to the outliner and select all other animations labelled &quot;action&quot;, except for your baked clip,

it will work. I must be creating some sort of workaround here, but at least it does work.
